An electronic diagnostics device can detect and report environmental conditions from manufacture to use. The device can include a reaction chamber configured to receive a biological sample and contain a reaction with the biological sample. A component of the biological sample can be detected based on the reaction. The device can also include one or more environmental sensors, such as a temperature sensor and a humidity sensor, to detect the environmental conditions. A processor can read data from the environmental sensors and compare the measured conditions to specified ranges. If an environmental parameter falls outside the specified range, the processor can disable the device or communicate to a user that the device should not be used to perform a diagnostic test.

A system for remotely retrieving sensed conditions at one or more building components. The building components are remote or numerous so that a wireless collection of the sensed conditions provides a significant benefit to a builder or building operator. A remote transceiver sends a wireless signal to a building component. The building component includes an onboard transceiver. At least some of the energy from the transmitted wireless signal is received by the onboard transceiver, sent to a storage device, and stored therein. The stored energy is used to operate a sensor for sensing an onboard condition. The onboard condition is then wirelessly transmitted by the onboard transceiver back to the remote transceiver to be displayed.
